Abstract

  An inflatable bag-like member having at least one fluid transport conduit operably connected to inflate / deflate the bag-like member; and an inflatable bag-like member A wound filling device for use in a device for performing local negative pressure therapy on a body part of a mammal is described that includes a textured separate cover socket member that covers at least a portion. An apparatus for realizing a wound filling device is also described.

Description

  The present invention relates to devices and devices for use in treating wounds with local negative pressure (TNP) therapy.

  In TNP therapy, a pouch-like member (also called a sac) that can often be used to fill, for example, at least a portion of the wound volume, into a bandage on a wound that is subjected to negative or positive pressure. Providing. In addition, fluctuating pressures or pressure cycles can be applied to the pouch-like member so as to work tissue in and around the wound area, eg, for therapeutic reasons.

  In US Pat. No. 6,099,056, a device, wound dressing and method for aspirating, washing and cleaning wounds are described. In general terms, the present invention provides a local negative pressure (TNP) therapy for aspirating a wound and additionally providing another fluid for washing and / or cleaning the wound, Describes the treatment of wounds by draining fluid, including both exudate and irrigation fluid, by means of suction and circulating through means for separating beneficial material from harmful material. The material beneficial to wound healing is recycled through the wound dressing and the material harmful to wound healing is discarded in a waste collection bag or container.

  Patent Document 2 describes a device, a wound dressing, and a method for cleaning a wound using wound suction, washing and cleaning. Also very generally described, the invention described in this document utilizes the same equipment as in US Pat. No. 6,056,075 for wound aspiration, irrigation and cleaning, but with a useful material returned to the wound site / bandage. It further includes an important additional step of providing heating means to control the temperature so that it is at an optimum temperature with the most effective therapeutic effect for example on the wound.

  U.S. Patent No. 6,057,051 describes an apparatus and method for aspirating, washing and / or cleaning a wound. Again, generally speaking, this document describes a device similar to that described in the above two documents, but provides a bioactive substance to the wound site / bandage to promote wound healing and Including the additional step of providing a means for administering.

  The contents of the above cited references are included herein by reference.

  All wounds addressed by the above documents may require the provision of a pouch or sac within the wound dressing, and what is currently available may be inappropriate. In fact, in US Pat. No. 6,057,836, an embodiment utilizing a pre-formed inflatable bladder used in a device for wound treatment is shown in FIGS. 13A and 20.

  Another reason in which inflatable sac type wound fillers may be utilized is that the surface of the sac surface is not flat, textured, or other non-smooth surface to the wound / interface This is because it is applied directly. The textured surface helps the “working” of the wound surface, thereby improving the therapeutic effect of the pressure cycle. The textured surface also distributes the pressure (negative pressure) more evenly on the wound surface so that fluids, such as wound exudate, from the wound area, generally toward the suction line that forms part of the TNP treatment device. A plurality of fluid flow channels are formed at the interface between the wound filler and the wound surface to help drain more quickly and uniformly.

  An example of a known inflatable wound filler is described in US Pat.

  In Patent Document 4, a wound cavity is filled using an inflatable bag or sac type wound filling member. Although the bladder member has been described as having two layers, the two layers appear to be in the form of a unitary structure. The problem with this type of structure is that it is difficult and expensive to manufacture. The structure makes the bladder relatively rigid and rigid, inflexible to the wound surface, and can cause discomfort and trauma.

  U.S. Patent No. 6,057,034 includes an inflatable bladder or sachet having a plurality of flexible conduits provided and extended within the bladder, the conduit having an outlet / entrance opening on the bladder surface. And / or a suction device. A conduit is a fluid transfer conduit for supplying fluid to the wound and / or for extracting fluid from the wound, or both. However, the problem with this particular structure is that manufacturing is very complex and expensive.

International Publication No. 2004/037334 International Publication No. 2005/04670 International Publication No. 2005/105180 International Publication No. 2005/082435 German Patent Application Publication No. 2378392 British Patent Application No. 0712735 International Patent Application No. 2007/074374

  The object of the present invention is to eliminate or at least mitigate some of the disadvantages of known device structures.

  According to a first aspect of the present invention, there is provided a wound filling device for use in an apparatus for performing local negative pressure therapy on a body part of a mammal, the device being an inflatable bag-like member An inflatable bag having at least one fluid transport conduit operably connected to inflate / deflate the bag, and a texture covering at least a portion of the inflatable bag And a separate cover socket member.

  The wound filling device described above can form part of a device for performing TNP therapy, for example, on a wound in a human body. Such a device is also connected to a suction means, such as a vacuum pump, for sucking a wound cavity defined under a sealing membrane or covering covering affixed to the intact skin or flesh around the wound An aspirated conduit generally can be included under which an inflatable bag and socket member are confined. At least one conduit operably connected to the inflatable bag for inflating / deflating can also pass through or under the sealing membrane or drape, but in all cases In accordance with the well-known TNP bandage structure. The execution of negative pressure can be accomplished by means or methods for draining from the wound area known in the art.

  The inflatable bag can be operably connected to suitable means for inflating via at least one conduit. Such means maintain a constant pressure in the bag or apply an inflating fluid, such as air, to apply a pulse pressure so that the wound surface acts to achieve a beneficial therapeutic effect on the wound. Well-known types of pumps can be included that can feed into and possibly draw out fluid.

  While the options for positive pressure expansion of the bag-like member have been described above, there are also options for self-inflating the bag-like member by leaving the connected conduit open to the atmosphere. Since the wound cavity surrounding the bag-like member is discharged, for example, by a vacuum pump, the bag is wound when one side of the bag surface is drawn toward the wound surface and the other side is drawn toward the inner surface of the hermetic covering membrane. There is a tendency to inflate when air is drawn only by the pressure difference between the cavity and the bag interior.

  The wound cavity formed under the sealing membrane or the peritoneum is also fixed so that excessive negative pressure is applied to the patient so as not to cause excessive discomfort when the sealing membrane is particularly effective for sealing the wound cavity. In order to maintain negative pressure, it is possible to have other conduits provided to provide ventilation to the wound cavity. Such vent lines also facilitate sustained suction of the wound cavity. Such additional conduits can also serve the dual purpose of utilizing pressure measurements at the wound when the pressure transducer is connected to the distal side of the wound.

  Other conduits with access to the wound area may also be provided to supply or administer cleansing agents and / or drugs to the wound site.

  The inflatable bag member and the socket member can be slidable relative to each other. Accordingly, when the bag-like member is expanded and contracted, for example, with a predetermined pressure pulse, the outer surface of the bag-like member and the inner surface of the socket member can slide relative to each other. This prevents the texture surface of the socket member from being slid forcibly with respect to the wound surface, can cause trauma, and can damage the newly formed granulation tissue. The outer textured surface can apply a pressure pulse substantially normal to the wound surface.

  By providing the inflatable bag-like member and the textured socket member as two separate parts made with known economical manufacturing techniques, several important advantages are obtained. First, the inflatable pouch can be made from an inherently soft and flexible thin sheet material that remains flat when folded or rolled inside the wound cavity, thereby creating a wound surface. Unnecessary loads and traumas are minimized as compared to known multilayer bag structures. The material from which the inflatable pouch can be made can be relatively thin because the pressure that it must withstand during inflation is relatively low. Next, by having a separate socket member on the inflatable bag-like member, the texture of the socket member surface is tailored to the needs of the wound surface and the appropriate socket / wound interface design to suit the wound type Can have.

  The socket member can be made, for example, from two sheet materials having substantially adjacent outer shapes and welded together at their outer edges. One sheet can have, for example, an opening into which an inflatable bag-like member is inserted, around which the socket member can be connected to the inside of the socket member without contacting the welded outer edge with the wound surface. Can be flipped over to include.

  Inflatable bag-like members are welded from thin flexible, substantially impervious plastic sheet materials such as EVA, PU, PP, PE, silicone and other suitable flexible plastic materials It can be produced in the same manner as the socket member that can be turned over so that it will later contain the weld inside. However, this is not as important as the socket member because the inflatable bag is contained within the socket member and the welded outer edge is not in contact with the wound.

  Thus, by having separate bags and socket members, each component is made to have properties that are optimized for its function and are not compromised due to the need to play two separate roles. be able to.

  In one embodiment of the inflatable bag member and socket member, the sheet from which they are made can be, for example, circular.

  The socket member can be molded as a combination with an inflatable bag-like member later.

  The conduit for inflating / deflating the bag-like member can be sealed with the bag-like member when entering the bag-like member. However, in a preferred embodiment of the invention, the inflatable pouch has an opening to allow fluid access to the inflatable pouch and advantageously fluid access to and from the wound area. The port member is attached to the opening by, for example, welding. Such port members may have provisions for connecting suitable fluid lines, such as flexible plastic material lines. The port member is also advantageously provided with a suitable shroud member, which provides a smooth rounded surface that does not cause discomfort when the patient sits on top, and more importantly The various ports serve the dual purpose of maintaining a free flow of fluid from the wound site without being blocked or blocked by the overlying sealing membrane. The port member and shroud provide the advantage that all conduits can be bundled together and treated as a single part, thereby making the device available for wounding more quickly and more efficiently, making the TNP device more reliable. improves.

  In a preferred embodiment of the present invention, in use, as described in US Pat. Access to the area can be provided.

  By manufacturing the device according to the present invention using a soft and flexible socket material, since the socket can be made of a material that does not substantially stick to the wound surface, and therefore less pain and trauma to the patient, The bandage can be removed more easily.

  The separate socket member of the device according to the invention facilitates the reduction of tissue growth that tends to close the wound and leave a cavity. The socket member effectively forms a member similar to the wound filler in conventional TNP treatments that prevents overgrowth of the wound and minimizes pocket formation within the tissue, either by secondary healing or by the wound Facilitates healing of the wound, upward from the base of the wound.

  The textured surface of the socket member primarily provides a uniform pressure distribution across the entire surface area of the wound and allows the surface of the bag / socket combination to drain the wound exudate efficiently and quickly through multiple channels. A plurality of channels can be provided on the top.

  In one embodiment of a socket member according to the present invention, the textured surface can include an array of hexagonal recesses or grooves that effectively form a three-dimensional surface structure on the surface of the socket material, each recess or groove being There is a hole in the center and both gaseous and liquid fluids can flow on both sides of the socket member, i.e. between the wound surface and the socket surface, and between the surface of the inflatable bag and the socket surface. It can be so. A suitable material from which the socket member can be made may be a vacuum formed plastic sheet material, such as an EVA film that is soft and does not stick to the wound surface.

  The socket member can be of any desired surface shape and form that is useful for wound surface treatment.

  Alternative materials from which separate socket members can be made include, for example, woven materials from a wide variety of different materials such as EVA, PU, PP, PE, silicone, carbomethoxycellulose, polyacrylate, nonwoven fiber sheets, foams, Electrospun nanofibers can be included.

  For example, biodegradable materials such as collagen, oxidized cellulose, chitosan, and polyglycolic acid can be used.

  In one embodiment of the present invention, inflatable pouch members, ports and shroud members, conduits, bandages and grommet members and socket members suitable for attachment to a patient can be supplied as an integral component, and TNP To be realized as a therapeutic device, it only needs to be applied to the wound and connected to a suitable source of vacuum and inflation fluid.

  According to a second aspect of the present invention, there is provided a device for performing a local negative pressure therapy on a body part of a mammal, the device realizing the wound filling device of the first aspect of the present invention.

  The wound filling device 12 includes an inflatable bag-like member 14 having a socket member 16 covering the outside. The inflatable bag-like member 14 is formed so that a weld bead 74 is formed on the outer periphery of two circular sheets 70 and 72 made of a thin plastic material having flexibility and impermeability. Are made by welding each other. The upper sheet 70 has a circular central opening 76 sized to be fixed to a thin flange 78 formed around the outer edge 80 of the port member 38. The flange 78 and the edge of the opening 76 are welded to each other so that the inflatable bag-like member 14 and the port member 38 are an integral part, or are joined together by bonding. The socket member 16 is manufactured from a thin plastic material having flexibility, such as EVA, and has a textured surface 80 formed in a vacuum. The surface shape of the socket member has an array of hexagons 82. Each hexagon is provided with a central hole 84 (not all recesses need to be drilled). Each hexagon is separated by a channel 86 as represented in FIGS. 2C-2E. FIG. 2F is a side view showing the outline of a hexagonal recess. Referring to FIG. 2F, the upright recess is adjacent to the surface of the socket member 16 when in use. The socket member is made of two sheets 90, 92 made of plastic material. Inside both sheets, a final wound contact surface 94 is disposed as shown in FIG. 2A. The two sheets are welded together around themselves, and a weld bead 96 remains outside the sheet. 2A and 2B show the socket member after welding and before inversion. A central opening 98 is formed in the upper sheet 90. After the sheets are welded together, the socket so formed is inverted about the opening 98, thereby forming a socket member as shown in FIG. 2C. As a result, a weld bead 96 is disposed on the inner side of the socket member, and a necessary textured surface 94 is formed on the outer side of the socket member.
